Board Optimization - Plugin Based Template Cache

Removed on author's request.

My PayPal link is under Mod Information on top of this page Glad to have helped out! (And make sure eAcc got enough memory so it doesn't start removing files. And you if really want to push it and got the PHP knowledge try the experimental version I'm running it for several months and it works really smooooth. Though I guess the performance gain is about the same. )

Will it help with my configuration - vb 3.6.7pl1, mysql 4.1.21 (mysqli in config), php 5.2, without any php cache and acceleration (as my shared hosting site5 doesn't allow that).
Any suggestions?

[orban]

This modification is for HIGH TRAFFIC vB installations.

[Fenriz]

orban, anyway it will not reduse the speed of my configuration, only help, right?

[orban]

Not it can make your installation slower, use more resources, RAM, cpu.

2 suggestions:
- Instead of another eval() call, just use an include() and make the include return the code
- Hook into template_compile to determine if a cache clear is necessary
This would also fire for style import, etc.

[orban]

1. How?

vB template calls are like this:

eval('$foo .= "' . fetch_template('bar') . '";');

fetch_template( ) returns the template as a string.

2. Is that hook new?

[Andreas]

1) Construct the file like

PHP Code:

<?php
return "template eval code";
?>

and

PHP Code:

$vbulletin->templatecache["$temp[title]"] = '".(include(\''. $path . $temp['templateid'] . '.php\'))."'; 


2) It's been there since the early 3.5 days

1) Alright that works too thought I doubt there's any performance gain. I only use the experimental version anyway which basically does what you suggest just with functions.

2) Hmm, is that function called for every template? Might be a bad idea to clear the template cache 100 times when importing a style...not to mention importing a style doesn't require you to clear the template cache in the first place...? But for clearing the cache when editing a template might be worth a shot.

[Andreas]

1) Probably not a noticable one, but there is one.

2) compile_template() is called whenever a template is saved.
If didn't mean that you shuld clear the cache in this hook, just that a flag that the cache is dirty.
This flag could then be checked in admin_complete and the cache cleared if set.
